Notes:

"In Oct. 1382, as the King's kinsman and young knight, he had a hunting licence."

"By the operation of modern doctrine he is held to have been Lord Mowbray and Segrave, but he and his brother John were styled respectively merely Thomas and John Mowbray when they were created Earls."

In June 1385, he was summoned for service against the Scots, and was in the vanguard in that—the King's first—expedition into Scotland.

He served under his father-in-law, the Earl of Arundel, in the naval victory over the French, Spanish, and Flemish fleets off Margate, 24 March 1386/87.

In Feb. 1387/88 he supported his father-in-law, the Earl of Arundel, as one of the Lords Appellant against the Duke of Ireland and other of the King's favourites.

In May 1390, "he was a commissioner to negotiate a truce with the Scots, and joined in the letter of the King and peers to the Pope, remonstrating against papal abuses in the Church, Parliament having called upon the King, in accordance with his coronation oath, to preserve the rights of the Crown and the liberties of the realm and Church."

In 1394 he accompanied the King to Ireland. He had licence to appoint a deputy at Calais on 26 August.

In January 1394 his crest of a leopard or, with a white label, to which he had hereditary right, and which was rightly the crest of the King's first-born son, if he had any, was directed to be differenced by a crown argent in place of the label.

In October 1395 he was one of the commissioners to contract the King's marriage with Isabel of France. He was presumably present at their espousals at Calais, 30 Oct. 1396.
